Thermoquads are not difficult to build at all, in fact, they are quite simple, I have several on my personal cars and build a ton of them. The biggest problems I see with them are when backyard engineers think that they are smarter than the engineers who designed them and start modifying them "To make them better". Bottom line? There is no "Voodoo", you simply need to learn how to adjust one properly which is also easy if you can read a technical manual and follow instructions. No, they are not the same as a Holley, so if that's all a person has ever messed with you'll need to open your mind and learn something new. not a big deal for most people who can turn a wrench. A good place to start is a factory service manual, there is also a good tutorial on the Imperial Club website. Imperial Club Site Link Here
